A piece of steel is taken from Earth to the moon for an experiment. The gravitational field strength on the moon is smaller than on Earth. Which statement about the piece of steel is correct?

• It has less mass on the moon than on Earth.

• It has more mass on the moon than on Earth.

• It weighs less on the moon than on Earth

• It weighs more on the moon than on Earth

Which statement about the masses and weights of objects on Earth is correct?

• A balance can only be used to compare weights, not masses.

• Heavy objects always have more mass than light ones.

• Large objects always have more mass than small ones.

• Mass is a force but weight is not
